SO FAR the Profumo affair has spawned a film, countless books, a Lloyd Webber musical and even questions in the House of Lords last week over secret papers connected to the events of 1963.

Mandy Rice-Davies (L) and Christine Keeler have had very different lives following the scandal [GETTY]

Now there’s more to come: one of its main protagonists is to divulge untold details about the sex scandal which rocked the British establishment.

Fifty years on, Mandy Rice-Davies is to write her “definitive”account (well she would say that,wouldn’t she, as she once perkily declared to the Old Bailey on being told Viscount Astor denied having an affair with her). She tells me: “I have been approached to write my life story and I will do it. After all, I’ve had an interesting life, haven’t I? Not that it’s over yet but I have plenty to say now.”

The Welsh-born model and her friend Christine Keeler were key figures in the furore which erupted after John Profumo, then Minister for War, lied in the Commons about his affair with Keeler, who was also sleeping with a suspected Russian spy.

The two good-time girls appeared at the trial of osteopath Stephen Ward, who was accused of living off the immoral earnings of both and later killed himself.

Mandy and Christine lifted the lid on a louche world of society orgies; even Prince Philip, a friend of Ward’s, was dragged into the maelstrom.

Since then, time has treated the two women very differently.

Keeler felt she was too notorious for normal life, too damaged for happy-ever-after and now lives alone in a council flat. Rice-Davies married a wealthy Israeli, describing her life as “one slow descent into respectability,” and now lives in Surrey with businessman Ken Foreman.

While Mandy, 70 this year, still looks glamorous, Keeler, 71, is unrecognisable from her days as the nation’s femme fatale. Neither of her two brief marriages left her with any money and she lives in South London with her cats. She used to work in a dry cleaning shop in Chelsea (where, incidentally, she used to iron my shirts).

Yet despite once being so close that they indulged in three-in-a-bed sessions with Douglas Fairbanks Jnr, she hasn’t spoken to her fellow showgirl for 30 years, claiming that Mandy had “rewritten history”.

She will not be happy that there is to be a new Rice-Davies account of the Profumo affair.
